Title: Apparatus and method for applying an easy-opening seal of adhesive tape
IPC: B65B61/18
Filed: 1963-03-21
Abstract: 1,043,262. Closing filled bags. MINNESOTA MINING & MANUFACTURING CO. March 21, 1963 [March 21, 1962]. No. 11308/63. Heading B8C. The ends of a flap-type seal (Fig. 8) of adhesive tape around a package or group of articles are prevented from adhering together either by inserting a piece of sheet material between the ends or by coating the adhesive with a non-adhesive material. In the form shown, the ends of the tape are stuck to the same side of a piece of sheet material M (Fig. 8). In the manually operated apparatus (Fig. 1) the adhesive tape T adheres to a flat platen surface 37 on an arm 32 pivoted at 33 and a paper strip P is fed around the arm 32 and through a slot 34 so that its end is adhesively secured to the end of the tape T. The neck of a bag is inserted through the opening 25 and pressed against the tape T which is thereby peeled away. Figs. 3-5 (not shown), from the platen surface 37, the arm 32 pivoting anticlockwise as shown. When the bag is forced against a pad 50 on a rocker bar 44, the latter operates a knife 42 to cut the tape and paper. On removal of the bag the arm 32 and rocker 44 are returned to their original positions by springs 38 and 49. In the electrically operated apparatus shown  in Fig. 9, a paper strip P from a roll 106 passes around a pivot plate 74 and through a slot 97 so that its end adheres to the adhesive tape T which is stuck to the platen surface 95. When a bag enters the machine its neck is gathered by two pairs of interlocking wheels 80 ,81, Fig. 10 (not shown), 82, 83. Latch fingers 121 are then moved to hold the neck of the bag in a recess 68 against the tape T. Simultaneously, a slide block 67 moves towards wheel 126, causing the tape to be peeled away from the platen 95 and be adhered around the bag neck and to itself. The slide block 67 also cams aside a pin 144 to operate a knife blade 139 cooperating with a recess 96 to cut the tape and paper, while a buffer plate 141 presses the remaining tape against platen surface 95. When the latches 112 are subsequently released and the block 67 retracted, a kick-out arm pivoted behind arm 121 ensures the bag is removed from recess 68 and the machine stops until a further cycle is initiated as a bag enters the machine. Initially the bag causes the switch arm 100 to disengage switch 104, but when the bag has passed the tip 103 the switch is re-engaged, causing the above cycle to operate. For an alternative seal the strip of paper P may be removed and a part of the pivot plate 74 removed by cutting along dotted line 145. A seal is then made with no paper attached, but with two free ends of adhesive tape which may be treated to render them non-adhesive or else adhered to a piece of paper or card. The card or paper may be printed. The machines may be adapted to wrap a number of separate articles together.

Pulping engines.-In a beater or pulping engine of the type described in Specification 174,985, the hood 7 is extended on the feed side by a guard-plate 19, Fig. 3, extending below the axis of the rotor 1, the blades 2 have their trailing sides 3 radial to the rotor and their leading sides 4 tangential to a circle of smaller radius than the rotor. On the delivery side is provided a radially-adjustable doctor 29, and a rubber flap 71, which latter is pushed aside by the discharged pulp. A gap 103 is arranged slantwise and connected to the top of the rotor casing which is maintained exhausted by the ejector action of the pulp. The bed-plate is held in contact with the rotor by the combined action of a spring and an adjustable weight acting through links and levers. To prevent leakage at the side of the rotor, discs 15 are provided of slightly larger diameter than the rotor and having alternate serrations 17, 18 set right and left handed. Pressing against these discs are screw rings 72, Fig. 9, grooved at 74, 74a to receive sealing water or lubricant supplied by a pipe 75. A cover 85 is secured to the casing 7 by bolts 79 which also secure diaphragm rings 78 fitting in grooves in rings 72. The space between the end 80 of the rotor and the cover 85 is supplied with water and vents 88 are provided. The threads of the rings 72 are reverse to the rotation of the rotor and excessive friction tends to unscrew the rings. The rings 72 may be pressed against the rotor by springs. In starting the beater, a priming valve 32, Fig. 1 supplies water to the pipe 13, and the space 20 between the rotor and hood is exhausted by means of a pump connected to the pipe 30. When the pulp rises to the top of the pipe 13 the priming valve is closed and the pulp falls down to the rotor. The vat of the pulping engine may be provided with a cover and the pulp raised in the pipe 13 by pressure. A pump may be used to assist in raising the pulp. The discharged pulp may strike an overshot wheel which, besides mixing the pulp, may be geared to the rotor to help to drive it. The rotor may have conical ends as in Fig. 8, bladed to co-operate with blades in conical shells, a separate feed 52 for each end being provided.

Abstract: 1,253,842. Fuel-injection pumps. C.A.V. Ltd. March 3, 1969 [March 8, 1968], No. 11378/68. Heading F1A. Fuel-injection pumping-apparatus for an I. C. engine includes a rotary cylindrical distributer member 11 carrying pumping plungers 13 in a bore 12 communicating with inlet passages 18 and a delivery passage 16, the plungers being actuated by an internally-lobed annular-cam 14 fixed to a body part 10 containing an inlet port 19 and outlet ports 17. Fuel is supplied by a rotary pump 20 through a passage 23 communicating with a stepped bore 25 containing a piston, or "shuttle", 26 and furnished with a stop 27. During inward movement of the plungers fuel flows into the narrow part of the bore 25, which is permanently connected to the bore 12, and into the left hand end of the widest part of the bore 25 by way of a non-return valve 28 until the piston abuts the stop whereafter the remainder of the fuel flows through the passage 16 to one of the ports 17. When bore 12 is being re-charged the piston ejects the fuel in the narrow part of the bore 25 back into the bore 12 while the fuel in the left-hand end of the widest part of the bore 25 is discharged through a variable throttle 29, which if closed prevents return movement of  the piston and so causes maximum discharge through the passage 16. The return movement of the piston may be effected by a spring rather than the pressure of the pump 20. The bore 25 may be formed in the member 11. Throttling means may be provided upstream of the port 19, to regulate the flow therethrough from the pump 20.

Abstract: 623,330. Covering wires with insulating material, UNITED STATES RUBBER CO. April 30, 1947. No. 11612. Convention date, Aug. 2, 1946. [Class 109] [Also in Group XXXVI] An electric conductor strand is covered by advancing a grounded strand through a receptacle to which short discrete fibres are supplied, a high electric field being maintained about the strand within the receptacle to cause the fibres to arrange themselves radially thereabout and finally laying the radially disposed fibres about the strand to form a cover. In a suitable apparatus a wire 10, from a metal supply spool 11 grounded at 16, is drawn downwardly through the fibres supplied to a rotatable non- conducting cylinder 12 of glass, transparent plastic &c. provided at its lower external part with a sleeve shaped electrode 13 of woven wire fabric connected to a source of high potential through a brush 17, rotation of the cylinder 12 causing the radially orientated fibres to wrap around the wire as it progresses therethrough. The fibres are supplied to the upper end of the cylinder 12 by means of a high speed pin-studded roll 38 producing air currents carrying the fibres downwardly therethrough, the fibres being fed to the roll 38 within a casing 37 from a film of fibres formed between an endless belt 30 and a curved apron 36, the belt receiving a charge of fibres from a doffer cylinder 27. The fibre-covered wire is then treated to compact the fibres around the wire by passing the covered wire through rotating wipers 53 pivoted to heads 52, 55 respectively provided at the ends of a hollow shaft 48 arranged below and rotated at higher speed than the cylinder 12 through which the fibre covered wire is subsequently drawn. A bounding fluid may then be applied to the covered wire 47 by passing it through a tubular die 59 having lateral passages communicating with an annular receptacle 60 containing the bounding material. After a final compacting by means of rotating wipers within a head 65, the covered wire is dried by passing through an air heater 66. In a modified apparatus, the sleeve-shaped electrode 13 is replaced by four wire electrodes spaced 90 degrees apart about the outer wall of the cylinder 12 connected to a slip ring which is engaged by the brush 17. In this arrangement the fibres tend to collect themselves into spaced groups between the central wire and each of the four electrodes instead of uniformly as in the first embodiment. The fibres specified comprise cotton, glass and particularly asbestos, short fibres being preferred. Covered wire with an intermediate " Vinylite' (R.T.M.) layer may be made. The bonding material specified comprises the product known under the R.T.M. " Vinylite."
